' DISPENSING APPABAT'C'S.

Application filed October 21, 1921. Serial No. 509,401.

whom it concern:

citizen, of the- United States, residing at Anderson. in the county ofMadison and State of vlndiana have invented a certain new vand usefulImprovement in Dispensing Apparatus, of which the following is a full,clear, concise. and exact description. -My invention relates todispensing apparatus and is of particular service in delivering measuredquantities of liquid fuel, such as gasoline, though the invention is notto be limited to any particular use to which itmaybe putt. v Theapparatus oi my invention includes a motor, a'feeding device operated bythe moto r,-and mechanism controlling the extent of operation of themotor and itself operated by the motor. When the apparatus is employedfor dispensing fluids the feeding de- Wice is in the form of a pumppreferably of the reciprocating type, that discharges a measuredquantity of the fiuid in each cycle of its operation. The motor isdesirably an 35 electric motor, the mechanism that controls the extentof operation of the motor being then inclusive of an electric switchthat is employed to place the motor in and out of circuit. This electricswitch is preferably manually operated in order to close it, the switchbeing held closed by a suitable stop thatyis deprived of .its functionwhen the predetermined. quantity of fluid has been pumped, the mechanismfor depriving such stop ofits function being operated by the mot9r. Themechanism that is operated by the *ihotor 'fordiscontinuing theinfluence of theZStop is made adjustable so as to vary the duration ofoperation of the pump according to the quantity of 'fluid' desired.

,;1 will explain my invention more fully by reference to theaccompanying drawings in which Fig. 1 is a front view with a portionoftl e, e uipment removed to reveal parts that wou ld otherwise behidden; Fig. 2 is a sectional view, online 22 of Fig. 1; Fig. 3 is. afront .view of a part of the structure whose illustration is omitted inFig. 1; Fig. a is a sectional viewonline 4-4 of Fig. 3; w Fig.5 is.asectional View on line 5-5 of Fig.

a; Figs. 6, 7 and- 8 .are sectional views respectively taken on lines6-6, 7-7 and 8-8 of Fig. 1 ;v and Fig. 9.is a diagrammatic view oftheapparatus. j

' ally Like parts are indicated by similar characters of referencethroughout the different figures.

The apparatus illustrated being one that s adapted to the dispensin ofliquid, there is employed a pump 1, pre erably of the recrprpcatmg type,that serves to transfer liquld, such as gasoline, from a suitable supplytank 2 to the flexible discharge hose 3, there being a check" valve 4 topermit withdrawal of the liquid from the tank on the outward stroke ofthe pump piston 5 and to prevent the return of the liquid to the tank-on the return stroke of the piston, during which return stroke theliquid is to be forced through the discharge hose 3. Another check valve4 is interposed between the pump and the discharge hose 3 in order toinsure the self-measuring aspect of the apparatus. A plurality ofoperations of the pump serves to eifect the delivery of a gallon of theliquid. The pump is preferably driven by an electric motor 6 that is indriving con nection with the pump through any suitable powertransmission mechanism such as the pulley 7 upon the motor shaft, a belt8 sur rounding this pulley, the pulley 9, the crank shaft 10 carryingthe latter pulley and the pitman 11 coupling the crank 12 with thepiston 5. Themotor may be operated by current furnished from anysuitable source, Fig. 9 digrammatically illustrating a source of directcurrent 13. The motor is connected in a bridge 14' across the generatormains, this bridge including in its circuit a .pivotmounted switch blade15 and a contact 16 with which the switch blade is in separableengagement. The switch blade may be thrown into engagement with itscontact 16 by depressing movement of the handle 17.

that is carried upon the handle lever 18 which is connected with thefree end of the switch blade 15 by a link 19. The lever 18 is pivotedupon the shaft 20 and carries two ear formations 21, 22 that arerespectively engageable with stops 23, 24 that define the range ofswinging movement of said lever. The pivoted end of the lever isenlarged and forwardly extended to receive the plunger 25 that isoutwardly pressed upon by a spring 26 that places the plunger in itsoutermost position when the switch is closed, at which time the plungerunderlies a stop 27 whereby the switch is maintained closed too until itis automaticall opened as will hereinafter appear. -At t e conclusion ofthe predetermined .operation of the, pump the motor operates anintermediately pivoted lever 28, throu h the intermediation of-mechanismhereina er to be described, such lever, in its operation, pressingthepostor linger 29 against the plunger 25 and depressing this plungeragainst the force of thes ring 26 to remove the plunger'from beneat thestop 27 whereupon the switch openin spring 30 is permitted to open theswitch, the luner being maintained in its dept i: adustment by. havingits outer end engaging the opposin face of the stop 27.

The switc opening spring 30 1s sultabl associated with the switch lever18. As 1 lustrated, this spring surrounds the rod 31 that is guided inits movement by an eye 32 throu h which one end of the rod 1passes, theot er end of the rod being pivota y connected with the outer end of thelever 18.

The mechanism whereby the motor may operate upon the plunger 25 when thepump 5 has been sufficiently operated is preferably inclusive of a spurpinion 33 upon the crank shaft 10, a spur gear 34 in mesh withthepinion, a worm 35 co-axial with and fixed with respect to the gear 34, aworm wheel 36 in mesh with the worm 35, a shaft 37 carrying the wormwheel 36, a disc 38 co-axial with and fixed upon the shaft'37 and theselected one of a number of buttons 39 that are adjustable into and outof the plane of the lever 28. When any such button is adjusted into theplane of the lever it is ultimately brought into enga ement with a post40 carried upon one end of the lever 28 olpposite the end that carriesthe post 29. T e but.- tons are arran ed in a circle that is concentricwith the isc 38 and its shaft 37. The buttons are desirablyequidistantly spaced, the space between any two ad'acent buttonscorresponding to a gallon. en the switch is closed the 0st 40 is s acedapart from the first button t at could engaged with it a distancecorresponding to one gallon. If this button happens to be adjusted intothe plane of the lever the pump willbe permitted to pump one gallonbefore such button engages the post 40 to open the switch. If the buttonin the second space from the st 40 is the one that is thrown into thepatbl ot the lever 28 the pump'will pump two gallons before it isstopped, etc. The drawings illustrate 16 buttons which permit theapparatus to be adjusted so that its pump may supply from one to fifteengallons according to its adjustment.

As illustrated in Figs. 4 and 5, the shank of each button has twoannular grooves 41, 42 and the disc carries a spring detent 43 for eachbutton, the unmounted end of eachdetent being engageable with one or theother of the grooves 41, 42 according the adjustrears ment of thecorresponding button into or out of the plane of t e lever 28. When adetent 43 engages the oove 41 in :the correonding button, suc button isheldin the s plane of the lever 28 and when the compan- While I haveherein shown and'particulap I 1y described the preferred embodiment ofmy invention 1 do not wish to be limitedt'o the precise details ofconstruction shown as changes may readil be made without "at; gartingfrom the s irit of my invention,'but aving thus descri ed my inventionI'cla'iin as new and desire to secure by Letters Patent thefollowing:- 1.
